The reason a country would want to use a crypto asset for their money supply would be to own the private ledger completely; they wouldn't utilize the decentralized, public, blockchains we see today.
All financial activity and transactions can easily be monitored on a blockchain; the movement of money could be tracked from it's inception to it's current location on one ledger. Each private key can correspond to a citizen (much like a social security ID) and citizens can be taxed more easily and efficiently. This is why China is leading the pack here and is already developing a PBOC digital currency[1].
In our case (Glaze), we are using a simple freemium model. The assets are free to use as long as the user attributes the illustrator and Glaze. If the user wants to buy a license so that they can use the image without crediting the artist/glaze, they can pay for that license (they also get a larger file size and the source file).
Unsplash is a bit different, all of the images are completely free. From my knowledge, this was originally used as a marketing funnel for their parent company, Crew. Crew has since been acquired and Unsplash has spun in to it's own entity. Nowadays my hunch is that they are monetizing through calls to their API (Unsplash is integrated into big players like Squarespace, Trello, Medium). Feel free to fact check as I am no expert when it comes to Unsplash's business model.
I was in a similar situation, I had offers from both companies and chose the startup, but ultimately ended up at Google.
I was up with the startup for 6 months, it was not a good fit for me and I lost faith in the company quickly. A recruiter reached out to me from Google while I was there to follow up. I did not need to re-interview and they brought me in since I was still in the system as an accepted candidate (I think this stands for one year). so I got to experience the best of both worlds. I’m still at google 2 years later, I can echo the sentiments of it opening up many more doors
